The wingless female died on the 6th, but the winged fcinale 

 lived on, without issue, until the nth of June. The period of 

 reproduction being 19 days with the winged female and 21 days 

 with the wingless, the former producing 40 and the latter 89 young. 



I found that the young moulted on the second, and began 

 reproducing either late on the seventh or early on the eighth day 

 after birth. The insects and plants were inspected, and the young 

 removed each morning, usually about 8 o'clock, so that the young 

 were the production of the subsecpient 24 hours.
